Abstract

A fiber Bragg grating sensor system for sensing a parameter, including temperature or strain comprises a structured sensor fiber Bragg grating in combination with a broadband light source, coupleer, readout grating mixing and spectral analysis system. The structured sensor fiber Bragg grating combination responds to an optical signal, and further responds to a sensed parameter, for providing a structured sensor fiber Bragg grating signal containing information about the sensed parameter. The broadband light source, coupler, readout grating mixing and spectral analysis system provides the optical signal, and responds to the structured sensor fiber Bragg grating signal, mixes the structured sensor fiber Bragg grating with a reference grating spectrum, for providing a broadband source, coupler, readout grating mixing and spectral analysis system signal containing information about a mixed and spectrally analyzed structured sensor fiber Bragg grating signal that is used to determine the sensed parameter.
